You're all missing the point - following the tsunami damage to their nuclear power plant, the white orbs are traces of radioactive dust hitting the sensor during assembly thus causing a shine path. The effect will outlast the sensors by 10,000 years (half life).
(Of course, if you believe this, you'll believe anything!).
apologies for bad editing - should read: '.... a bit more pocketable.....'
Hi Francis - re your comments, I looked at the spec for the upcoming Canon G1-X and gave it some thought but decided that the X10 dimensions made it a bit more pocketaalsoble (which it is, and believe it or not, I must admit that the neat retro-style also swayed me a bit!). Seriously though, I seldom print larger than A3 for competition or demo work, most of the time, committing images to disc for AV presentations. Naturally, the Nikon is used for wide angle and telephoto pics. For everyday images I find the X10 gives fairly good definition corner to corner and I enjoy the Fuji inbuilt choices of 'film types' (Velvia, B&W filtered effects, etc) saving a bit on Photoshop time. The X10 fast f2.0/2.8 lens was also very acceptable.
Having been a photographer for some forty years, I've never yet had a camera that has been 'perfect', but having been through the days of wet chemical processing I'm glad I'm living through this digital age of being able to carry around 'a darkroom in my pocket'.
At one time, using a Canon S45 as a backup to my Nikon gear, I had to return two S45's until I got 'a good one' (one of the returned units even had tiny metal filings prevalent behind the front lens element). My current Canon S90 unit has performed quite well, but looking for something new led me to purchasing the Fuji X100. I stuck with it for three days - but felt it had too many quirks and it wasn't exactly a 'fast' shooter.
That's how I ended up with an X10 about a month ago. Tried it and liked it and as yet, found no reason to give up on it. Maybe I've had 'a good one' and will admit that if I need to use it quickly, I put it straight into Auto mode - which has not disappointed!
